LIs'rED-ooim-oUL'rIvAToR-ooNvERTINo MEANS.

Application filed October 19, 1925. Serial No. 63,405.

s The general object of my present invention is the provision of means whereby a two row listed-corn cultivator can be expeditiously and easily converted into a three row cultivator. V

' Another object of'the invention is the vprovision of means for the purpose described characterized by a member having an angular loop whereby a third gang unit is given the advantage of the useful roller means forkeeping the said gang unit in parallelism with the other gang units, the same member also rendering it feasible to place the third gang unit a little behind the other twogang units, thereby affording greater space for the disks and shovels of the several gang units for oscillation side by side without interference with each other,

and to permit vertical oscillation of the third or added gang unit independently of the other gang units as when the cultivator is traversing uneven ground. 7

Another object of the invention is the provision of improved means for hitching the three row cultivatorto a tractor or the like. V

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed. g

In the accompanying drawings forming part of this specification I Figure 1 is a topplan View illustrating my improvement when a two row listedcorn cultivator is converted into a three row listed-corn cultivator.

Figure 2 is a perspective illustrating the loop bearingmember constituting an important feature of my invention and the appurtenances of said member.

Figure 3 is a detail view illustrative of a portion of the hitch.

Similar numerals of reference designate corresponding parts in all of the views of the drawing.

In Figure 1 of the drawing, I show the cultivator as comprising three gang units numbered 1, 2 and 3; the outer gang unit being similar to those ordinarily used in a two row listed-corn cultivator, and each having shovels 4: and disks 5 attached to a bar 6, of angular form in cross section, which bar 6 is carried by a bail-shaped frame 7, supported by ground'wheels or rollers 8, and connected at 9 to a forwardly reaching frame bar 10. It will also be the before mentioned .cross bar '13.

noticed that each of the units 1 and 2 com prises beams 11 and thus the two units 1 and 2 are connected together through the medium of a transverse bar 12, the said bar 12 being connected to the frames 7 of the two'units in the ordinary well known manner or in any other'manner compatible with the, purpose of my invention. The frame bars 10 are connected to a transverse bar 13, and carried bythe said bar-13 is a heavy strap iron 14, disposed as bestshown in Figure 3, so as to lower the hitch as isfldesirable. 1 By reference to Figure 1 it will be observed that rods 15 arecarried by and extend from the frame bars 10, and-in accord ance with my invention the 'member 16 which constitutes an important factor thereof is mounted on and connected to the rods 15, by preference, insuch manner'that the member 16 is capable of rocking about its axis. At its middle, the shaft or rod like member 16 is provided with a laterally defiected or angularly disposed loop 16 which also constitutes an important feature ofmy invention.

The third gang unit numbered 3 is connected at 20, Figure 1 to the loop 16",.and it will also be noted that the bail-shaped frame 7 of the gang unit 3 its forward end or bight portion to a forwardly extending supplemental bar 21,

which latter is detachably connected at its forward end in an appropriate manner to From is connected at this and the remainder of the improved construction as described, it follows that when desirable the threerow be expeditiously and easily into a two row cultivator.

Manifestly the member 16 positions the central gang unit 3 in such manner that said gang unit3 operates slightly to the rear changed back 'of the other gang units 1 and .2, with the result that more space is afforded for the disks and shovels of the several gang units to oscillate laterally without I interference with each other; also, with the connection of the gangunit 3 to the member 16, the unit 3 is under the influence of the useful roller means for maintainingv the unit 3 in parallelism with the other units 1 and 2. Moreover, on uneven ground and incident to the traverse of the cultivator, the central gang unit 3 is enabledby virtue of its cultivator may I described connection to the members 15 to oscillate vertically with the result that the efficiency of-the ground engaging elements, of the un1t3 is materially increased.

It will he'further apparent from thefore going that the construction described con stitutes a hitch for nsein co njnnotion twith the tractor. and one that is rigid for some stretches and fieXibleforother-s and at thesame time While light in weight is ell adapted to Withstemd the usage in which' such constructions are ordinarily suhj eoted.
